Osl (Osli, Osth or Ozsol) was the name of a gens (Latin for "clan"; nemzetség in Hungarian) with Hungarian origin in the Kingdom of Hungary, based in today's Győr-Moson-Sopron County and in the Banate of Severin. The village of Osli was named after that clan. Also the Oslea mountain in the former Banate of Severin.
